INSTRUCTIONS OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention is an improvement in bicycle and pedal power traffic systems that achieves tradition through a chain or belt: improved to reduce in the cycle of pedaling Static point effect:: Optimization of the stepping power system. See the foot [Previous technology] Since the end of the ninth century, many people have expected to increase the effect of the bicycle and reduce the static response. Specifically, almost all pedaling power is on the treadmill =. When the crank arm and the top static point are about 9G degrees, the pedal power is the most. When one of the pedals is on the top and the other is on the bottom, since the force applied to the pedal has almost no tangential angle, a power blank area, which is called a static point, is formed. ^ Many of the above attempts have been made by using non-circular or "elliptical," links that are elliptical or other more complex links of various or curved or straight members' diameters. There are various combinations of major diameters and minor diameters. There are also various other attempts, such as the use of independent cranks to optimize the dynamics of each leg. Until today, look at these from the physiological point of view. Calling the evidence is the most effective way to optimize the pedal system. 0 Among the above methods, we can simply enumerate the two types of key faults on the market recently [Shlman〇Bi〇Pace link (US Patent No. 4522610) No.) and Osymetric link (US Patent No. 5549314). Of course, there are some earlier documents: US Patent No. 513589, US Patent No. 515449, British No. 1379959 Patent No. 191318888, French Patent No. 645447, British Patent No. 327681, French Patent No. 1〇9〇949, Danish Patent No. 6451 Zha and British Patent No. 449504' and a more recent U.S. Patent No. 5882〇25 These patents 'apparent' ® oval-shaped "link ultimate success is widely use. In the prior art, particular attention should be paid to French Patent No. 1,090,949, which is similar to the present invention in terms of the positioning of the elliptical link of the multiple I. The purpose of the different links described above is to provide greater thrust to the bicycle by utilizing various drive radii by utilizing the area of maximum power of the pedal cycle. To achieve this, consider three design factors: • Positioning factor: the angle of the main diameter of the crank centerline and the elliptical link, which is the same as the top dead point (general) of the crank when the maximum gear ratio is reached ( When the maximum radius is converted into traction); • The elongation factor: the ratio of the major and minor diameters in the elliptical link, to the 幵y-like coefficient. It depends on the circumference of the elliptical link formed by the curve (ellipse, circumferential arc) , straight line areas, etc.) - None of the elliptical links mentioned above have been successful in the market. Although each link has been improved in some way, so far: What kind of chain link can combine all the improvements to achieve success. The main reason for the lack of success is due to invalid positioning factors. Since every method of riding a bicycle is different, it cannot be said that these products will not work. Actually, the product is still popular with many people. However, the positioning coefficient is the key to the physiological mechanics of the foot. Even if these positions are accepted by a small number of people, most of them are still ineffective. 6 1379959 ^For example, the BlQPaCe chain may be effective for some people, but the result is still missing on the market. The extension coefficient and shape factor of the link can also be connected, and the == number is too slow. That is to say, the ratio of the crank arm to the top dead point is too late, almost coincident with the treadmill at the bottom end (10). Get the big gear

factor of the Osymetrics link is quite sharp, such as most of the 3 round links. When the crank is in the maximum area of the pedaling force, the large gear ratio is achieved, so that the inertia can be utilized without generating a constant delay. Due to its form and elongation factor, the speed changes around the static point, which is unfavorable for the knees. This is why many people give up the chain, and the chain ring can play a good role for the strong rider. In the ::; car = cyclist's ~, can not be = heart f country patent No. 1 〇 9_ number of adjustable key ring involved in the positioning she is not accurate ' at the same time its combination of extension coefficient and shape factor non = no This does not allow for the combination of various factors that have advantages.钇疋Because he uses the independent crank to realize the treadmill ^ ^ ^ chain links, which are connected by connecting rods, two:: effect::::: the smallest to the smallest is not synchronized, the degree of its offset ^ : Giant: The speed of each crank is also different. When a crank slows down == Shen, the force applied in the toe cycle is as fast as it is and the first one is at the bottom. The other crank moves (TDC). The m point (BDC) exceeds the top static point. With regard to this method, the spleen patent is _year's German special 7 1379959 Lie 76215, which determines the basic structure of this chain. Another invention of the inventor of the present invention, the RS4 link (U.S. Patent No. 2/5/22226 Al), is being marketed under the names RS4 and RS4, and has achieved remarkable sales results. For this kind of link, two parameters or design coefficients need to be considered: 乂·Positioning coefficient: When the gear ratio is maximum, the angle formed by the falling crank arm and the top static point, or the same positioning of the elliptical link Coefficient, · • Centrifugal coefficient: The relationship between the maximum and minimum drive ratios, related to the elongation factor of the upper elliptical link. Although the RS4 link has not been widely used, it has been used by several riders around the world. Its experience clearly shows that the positioning factor plays an important role in the physiological wind of the treadmill: the optimal position of the maximum gear ratio - the optimal positioning factor is delayed when the maximum force is applied. Therefore, even if the optimal positioning factor is not = it depends on geometric data and kinetic data, we can still try to locate the previous elliptical link. Marsh Jin = Description: The He Xue data determines the position where each rider performs the maximum torque transmission. Geometry data includes bicycle geometry, the second degree of the seat, and whether the rider is sitting or standing on a treadmill. At the same time, the rider's body and weight also play a very important role. The above-mentioned kinetic poor material mainly includes the change of inertia when treading, and the crank position and the gear ratio reach the maximum when the maximum torque is transmitted. ^^ Legs Of course there is no fixed value because of the offset of this Β. In the case, for example, Pingdi or Xinpo, sitting and riding a bite to stand on the different treadmills. Ride on the secondary station, or the rider's fast light or all of the above factors that will affect the optimal positioning factor. To achieve widespread use, universal principles are needed for the needs of the car. The solution is to meet different rides. The above Rotor links are generally 6 (1) degrees, but in the end the different riders set the money between the top dead spots (TDC). Top dead point (TDC) and bottom: 'dry circumference is usually in the position of 103 to (8) degrees ^ bicycle bottom (four) (coffee) position is the rider's hips, because ^ϋ77 not n##ai shaped key ring The design is not rational enough for some::: At the same time, although a certain type - the type uses the perfect type.

The tenth 仃 π is about to improve the individual [invention] The imitation = two r:: the link, in principle, by the maximum force generation stage to the rotor Qu Zhizi can achieve a similar power source, although it does not reach the crank degree. This is because it is necessary to choose a smaller extension of the same extension to prevent sudden changes in the speed of the leg at the edge, as it is desirable to maintain the constant speed of the month b in this area. In order to do this, it is necessary to minimize the change in the drive radius during cycling: the instantaneous gear ratio of a 53-tooth R〇tor link is from a minimum of 47.6 to a maximum of 58. 8 (in off-road or When going up and down, the: may be larger, and the new 53-tooth elliptical link changes between 5〇. 9 and 5 5. 9.

[Embodiment] 实施, the embodiment -., two, five, six And the elliptical links shown in the seven figures are ideal for the conventional cranks (〗 〖2,} 2) of the present invention; the shaped links (1), 11'). The chain (].) is indicated by the dotted line: the first: the wheel, when the maximum is reached, the chain (10) and the chain (1) two: the shape of the key ring is adjusted, (10) the positioning of the turtle, the second load 32 is the top static point (10) The positioning factor of the reference. For 1379959, depending on the source of the chain (for example, from the use of key gears at any time) and the geometry of the bicycle (connection base and 长度^2, length and angle of the support), there may be subtle changes. ^, 支 The second figure shows that the crank (12, 12,) device shown above shows the change of the life = the difference between the applied link (1) and ln. This design shows that the initial positioning factor is located at 8 离 from the crank arm. In addition, this design provides special positioning and adjustment of the hole (13) connected to the conventional crank arm (14). There are 35 holes (13) adjacent to each other 10. 286 〇 (= 36 〇 0/35). This sound is two, and one crank rotates 17 holes, which is 174.857. , its effect and installation one = oblique Tang Meng Department 曰 4 Li λα I», a 5. 14 3 Ϊ hole retreat can be arranged more closely, and even make them reciprocal as the ninth ^ - Causes unacceptable damage to the structure. =:= to separate the inner and outer circumferences of the hole to form two holes. Gear ratio. This, the same, the instantaneous rate of a 53-tooth extended circular key ring, when the number written next to the pedal 1 ^ _ point is the corresponding gear gear data is effective when the crank is made to the mark position Then adjust and live accordingly. 'Because the positioning coefficient is determined by the manufacturer's own figure;: t or downward adjustment' is the change of the chain and link occlusion vector caused by the same pair of gears related to the position of the crank arm. It also has a subtle effect on the positioning factor of the map. The fourth picture is for ==RS. 4 Requires: 1: The size of the corresponding link of the f3 tooth link is determined by the knot and is determined as ΐί 'Because the positioning coefficient is adjusted by the user to adjust the clockwise direction 'the figure related to the crank arm position' The hole of the -2 === (53) indicates the original direction of the selection. Other holes are used to effectively adjust the positioning of the mark. Also, in the standard adjustment of the larger road bike link, it is recommended to determine the curvature = direction, the crank (12) anchor hole (53) is positioned at the position of the chain and the maximum j of the link (ι), the crank ( 12) The distance from the top static point is approximately 1〇5. "The ampere & 1" ° for the 53-toothed key ring (1)), the above angle is about 108. > a2 in the picture. The actual angle between the top dead point (TDC) and the crank 2) midline in the initial adjustment depends on the chain (} Q) and the link ((1) merging vector. Usually, the standard positioning value is adjusted in 丨〇〇 Between the two 〇 〇 。 较大 较大 较大 较大 较大 较大 较大 较大 较大 较大 较大 较大 较大 较大 较大 较大 较大 较大 较大 较大 较大 较大 较大 较大 较大 较大 较大 较大 较大 较大 较大 较大 较大 较大 较大 较大 较大 较大 较大 较大 较大 较大. Between the two, depending on the meshing vector of the chain and the link, and the kinematics of the chain under normal use conditions. 53 The toothed chain has an elongation factor of 11〇, allowing for a reasonable change between the maximum and minimum speeds of the pedal. As with road bikes (racing)*, taking mountain or 1379959 recreational bicycles as an example. This value may be slightly larger due to the larger negative (9) of the pedals. To solve the problem of powertrain or transmission compatibility. = The length coefficient can also be reduced. Its variation value is between h 〇75 and 丨, 125. Finally, the shape of chain % (11) is elliptical, and the diamond shape formed by the center of its four perimeter arcs has a Sharp angle (see Figure 6). The perimeter coefficient of the ellipse should be 〇. 993. The seventh diagram depicts the kinematics design of this chain. It can be seen that when the average is greater than the average, the time for the bicycle to turn one more time is about (10). The change is minimized, and the knee comfort is improved. When the speed is less than the average value, the bicycle turn-week time is about 5 (10) less, which is combined with the movement of the ankle angle during the pedaling process. This method is realized: Speed. The change in the speed of the leg pedal is also the most other embodiment of the elliptical link. The shape factor allows for small changes in the initial circumference, although the ideal now results in a straight section of the acceleration peak or other large radius curvature. Is the elliptical circumference or mixed circumference mentioned, that is, the ellipse is set in the first and first regions, and the ellipse is in the second and fourth quarters - (iv). (4) Deceleration and ς There may be obvious changes. The above-mentioned elliptical II-shaped chain ring is used on the traditional crank, different types of links. Each type is in accordance with the description of the present invention, only slightly on the If coefficient.

Time will be more than sitting on the treadmill" column When the car reaches the maximum torque, the torque on the smaller link is delayed. The standing treadmill usually acts in terms of the positioning factor. For example, the adjustment method can refer to the crank and the inner ring: the detachable one is available. Selecting the lower point between the crank and the inner ring and in this case the eleventh figure of the alternative item II according to the invention, which is to simultaneously change the link and the crank: positioning adjustment Scope, 成,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, Mining = :; ("α第=数: r in: Applicable to four-arm crank.
